Key features of Saltasaurus include:

• Armor Plates: Saltasaurus had a series of bony plates embedded in its skin, forming a sort of armor. These osteoderms were scattered across its back and sides and likely provided some defense against predators.
  
• Small Size: Compared to some other sauropods, Saltasaurus was relatively small, with lengths estimated to be around 30 to 40 feet (9 to 12 meters). It was a member of the titanosaur group of sauropods.
  
• Herbivorous Diet: Like other sauropods, Saltasaurus was a herbivore, using its long neck to reach vegetation high in trees.
  
• Quadrupedal Posture: Saltasaurus walked on all four legs, like most sauropods. Its front legs were slightly shorter than its hind legs, giving its body a slight tilt.
  
• Diverse Teeth: Fossil evidence suggests that Saltasaurus had various types of teeth adapted for chewing plant material, which indicates a diverse diet.
  
• Discovered in Argentina: The fossils of Saltasaurus were discovered in Argentina, and it was named after the Salta Province where the remains were found.
  

The discovery of Saltasaurus contributed to our understanding of the diversity of sauropod dinosaurs and their adaptations to different environments. Its unique armored appearance sets it apart from many other sauropod species.
